1. A method performed by a computing system, the method comprising:
obtaining an input audio signal comprising one or more input audio elements, wherein the one or more input audio elements comprise one or more rhythmic components;
generating one or more modulated audio elements by modulating at least a portion of at least one of the one or more input audio elements of the input audio signal with a modulation signal, wherein the modulation signal comprises both (i) a fundamental modulation rate less than 40 Hz and (ii) a modulation waveform arranged to cause one or more neural oscillations at rates different than the fundamental modulation rate of the modulation signal in a brain of a listener above the fundamental modulation rate of the modulation signal;
creating an audio output signal by mixing the one or more modulated audio elements of the input audio signal with one or more unmodulated portions of the one or more input audio elements of the input audio signal; and
wherein generating the one or more modulated audio elements of the input audio signal comprises causing both of a modulation phase and the modulation rate of the modulation signal to align with the one or more rhythmic components of the one or more input audio elements of the input audio signal.
